Embodiment 1
[0025] An automatic test system for remote measurement accuracy of power system measurement and control devices, such as figure 1 As shown, a command component 100 for connecting with a relay protection tester, a test configuration file library component 200, a simulation master station component 300 and a judging component 400 for connecting with a measurement and control device are provided;
[0026] As mentioned above, the command component 100 is connected with the simulation master station component 300, and the simulation master station component 300 is connected with the test configuration file library component 200 and the judgment component 400 respectively;
[0027] Specifically, the command component 100 issues a test command to the relay protection tester, and the relay protection tester sends the corresponding test data to the measurement and control device according to the test command, and the simulation master component 300 calls the slave test configuration fil...
Embodiment 2
[0068] An automatic test system for telemetry accuracy of a power system measurement and control device, the other structures are the same as in Embodiment 1, the difference is that the telemetry accuracy automatic test system of a power system measurement and control device is also provided with a communication protocol analysis and conversion component 102, the communication protocol analysis and conversion The component 102 is connected to the command component 100 and the command interface 101 respectively.
[0069] Specifically, the communication protocol analysis conversion component 102 is configured as an RS232 serial communication protocol analysis or RS485 serial communication protocol analysis or RS422 serial communication protocol analysis component.
[0070] By setting the communication protocol analysis conversion component, the mutual communication efficiency between the system and the relay protection tester can be improved, and the stability of the system opera...
Embodiment 3
[0072] An automatic test system for telemetry accuracy of a power system measurement and control device, the other structures are the same as in Embodiment 1 or 2, the difference is that, specifically, there are N test data feedback interfaces 402, N≥1, and N is a positive integer.
[0073] Specifically, the judging component 400 is provided with M sub-judging units 401, and the sub-judging units 401 are matched and connected with the simulation master station component 300 and the test data feedback interface 402 respectively, M≥1, and M is a positive integer.
[0074] In this embodiment, there are five test data feedback interfaces 402 and five sub-judgment units 401 respectively, which can increase the test effect of the system on the measurement and control device.
[0075] In the actual use process, the number of test data feedback interfaces and sub-judgment units can be adjusted in time, such as being set to 3, 6 or 7 at the same time, etc., and adjusted according to the...
